6. A coil of wire with an electric current flowing through it becomes a
magnet.

7. Putting iron inside a current-carrying coil increases the strength
of the electromagnet.

8. A changing magnetic field induces an electric voltage in a
conductor.

9. A charged particle experiences no magnetic force when moving
parallel to a magnetic field, but when it is moving perpendicular to the field it
experiences a force perpendicular to both the field and the direction of motion.

10. A current-carrying wire in a perpendicular magnetic field
experiences a force in a direction perpendicular to both the wire and the field.
